Answer:
If we have a set of N elements:
{x₁, x₂, ..., xₙ}
The mean value (also called the average value) Is calculated as:
Average = (x₁ + x₂ + ... + xₙ)/n
So if x is the average of 13, -16 and 6 ( a total of 3 values)
x will be equal to:
x = (13 + (-16) + 6)/3 = (19 - 16)/3 = 3/3 = 1
x = 1
And we know that:
y = ∛8
Remember that:
2*2 = 4
and
4*2 = 8
then
2*2*2 = 2^3 = 8
then ∛8 = 2.
So we have:
y = ∛8 = 2
Now we can replace these values in the equation:
x^2 + y^3
replacing:
x = 1
y = 2
we get:
1^2 + 2^3 = 1 + 8 = 9
! Means starting from that number multiply by every number down to 1.
5!= 5•4•3•2•1 = 20•6=120
2!= 2•1=2
120+2=122 :)
Answer:
D
Step-by-step explanation:
If f(x) = 4x ^ 2 - 3 and g(x) = x + 1 , find (f - g)(x)
A. 4x ^ 2 - x - 2
B. x - 4x ^ 2 - 2
C. 4x ^ 3 - 3
D. 4x ^ 2 - x - 4
(f - g)(x) = f(x) - g(x)
4x ^ 2 - 3 - (x + 1 ) Multiply the brackets by the negative.
4x ^ 2 - 3 -x - 1 Add like terms.
4x ^ 2 - x - 4 Final Answer
